Diyabetik Retinopatisi Olmayan Tip 1 Diyabet Olgularında Retinal Mikrovasküler Yapıların İncelenmesi

Öz

Amaç: Sunulan çalışmanın amacı retinopati tespit edilmemiş tip 1 diyabet olgularında, optik koherens

tomografi anjiyografi (OCTA) bulgularının değerlendirilmesidir.

Materyal ve Metot: Çalışmaya 11 tip 1 diyabet olgusunun 17 gözü ve 18 sağlıklı gönüllü olgunun 36 gözü

dahil edildi. Optik koherens tomografi anjiyografi görüntüleri, mikrovasküler değişikliklerin varlığı

açısından değerlendirildi ve yüzeysel kapiller pleksus (SKP) ve derin kapiller pleksus (DKP) seviyelerinde

foveal avasküler zone (FAZ) alanı ve vasküler densite (VD) ölçümleri yapıldı.

Bulgular: Optik Koherens Tomografi Anjiyografi incelemelerinde, 11 tip 1 diyabet olgusunun 7’sinde

mikrovasküler değişiklikler izlendi. Diyabetik grup ve kontrol grubu arasında SKP ve DKP seviyelerinde

yapılan faz ölçümlerinde anlamlı bir fark izlenmedi (sırasıyla p=0,647, p=0,874). Diyabetik grup ve kontrol

grubu arasında SKP ve DKP seviyelerinde yapılan VD ölçümleri arasında da anlamlı bir fark yoktu (p>0,05).

Sonuç: Klinik olarak diyabetik retinopati tanısı almamış diyabetik olgularda, retinal mikrovasküler yapıda

harabiyet gelişebilir. Optik koherens tomografi anjiyografi, erken evrede gelişen mikrovasküler bulguların

tanınmasında faydalı olan, hızlı, girişimsel olmayan ve güvenli bir görüntüleme yöntemidir.

Evaluation of Retinal Microvascular Structures in Type 1 Diabetic Patients without Diabetic Retinopathy

Abstract

Objectives: The aim of the present study is to evaluate the optical coherence tomography angiography (OCTA) images in patients with type 1 diabetes who have not been diagnosed with retinopathy.

Materials and Methods: The study included 17 eyes of 11 patients with type 1 diabetes and 36 eyes of 18 healthy volunteers. Optical coherence tomography angiography images were evaluated for the presence of microvascular changes and measurement of foveal avascular zone (FAZ) area and vessel density (VD) measurements in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) were performed.

Results: Optical coherence tomography angiography revealed microvascular changes in 7 of 11 type 1 diabetes cases. There was no significant difference between the FAZ measurements between the diabetic group and the control group at the SCP and DCP levels (p=0,647, p=0,874 respectively). There was also no significant difference in VD measurements between the diabetic group and the control group (p> 0.05).
Conclusion: In diabetic patients who are not clinically diagnosed with diabetic retinopathy, retinal microvascular damage may occur. Optical coherence tomography angiography is a rapid, noninvasive, and safe imaging modality that is useful in the recognition of microvascular findings that develop at an early stage.
